Darstellung und Eigenschaften der Aluminium‐Oxid‐ und ‐Thiohalogenide Erzeugung eines Oxid‐ und eines Thioamids

Abstract

Drei Aluminiumoxidhalogenide ‐ AlOCl, AlOBr und AlOJ ‐ werden dargestellt und eingehend untersucht. In ähnlicher Weise werden die Thiohalogenide ‐ AlSCl, AlSBr und AISJ ‐ bearbeitet. Einwirkung von NH3 führt zu einem Oxidamid bzw. Thioamid, von NH2(CH3) zu einem Methyloxidamid bzw. Methylthioamid.

Intercalation Chemistry of Metal Chalcogenohalides

“…The most convenient method (J, 5) appears to be the sealed-tube reaction of excess A1C1 3 with As 2 0 3 at 250°C; upon completion, AsCl 3 AICI3 can be separated from the colorless, microcrystalline product by sublimation.

“…Aluminum thiohalides (A1SX, X = CI, Br, I) have been prepared via the sealed-tube reaction of A1 2 S 3 and A1X 3 (7,9,10). Like their AlOX counter parts, they are colorless microcrystalline powders that react readily with water at 25°C to give y-ΑΙΟΟΗ.…”

“…Colorless crystals of indium oxychloride and oxybromide have been prepared by the sealed-tube reaction of In(OH) 3 and H 2 0 with the appropriate indium trihalide (15) or by treatment of InOI with Cl 2 or Br 2 at elevated temperature (2).

“…Recently, such reactions have received a great deal of attention (16,33,34,42,54,(58)(59)(60)(61)(62). With pyridine, the stoichiometry is variable; Koizumi re ported that below 60°C, FeOCl reacts with pyridine vapor to give FeOCl-(pyridine) 1 / 4 whereas, above 60°C, it gives FeOCl(pyridine) 1 / 3 . The stoichiometries were derived from a combination of weight gain and ele mental analysis.…”

“…Resistivities of the other intercalates vary from 10 3 to 10 2 Ω cm, and in all cases the thermo electric power is negative, suggesting that the charge carriers are electrons (34). While all of the above studies deal with FeOCl or VOC1 as host lattices, isolated reports of intercalation of trimethylamine in AlSeX and A1SX (X = CI, Br, I) have appeared (3,11). The most recent study shows a small increase in the value of the isomer shift and a decrease in the quadrupole splitting, compared to FeOCl (54,69).…”
